Part of the problem is you have to be able to strop well to effectively use paste in progression and these paste are pricy, about 40-50 dollars per bottle. And you would need at least 2 progressions.
Your best bet is a 3/8 or 4/8k combo stone, then good Chrome Oxide.
If you are talking about your Hard Ark at 11um, any natural stone does not have a grit rating, as they are naturally made and have random grits.
Many have used an Ark progression for over a hundred years, with just an soft and Translucent or Black Surgical Ark with great results.
It can be slow and will take some time to learn.
There is much written on this forum and other on honing razors with Arks.
